Not the End of Process

If a knowledge worker has the organization’s information in a social context at their finger tips, and the organization is sufficiently connected to tap experts and form groups instantly to resolve exceptions — is there a role for business process as we know it?

Yes. There are some interesting comments spurring by this post but essentially I think the post is in no way a compelling argument that process management is not a very good management practice.
In a response to the original post, Nicholas Carr wrote an excellent post, Process Matters:

Structured, well-thought-out processes are also essential to most knowledge work, from product development to financial analysis to software engineering to sales and marketing. And the more complex the effort, the greater the need for clear processes. Far from making business less effective and agile, the increasing attention to process has increased effectiveness and agility.
